using tub & tile caulk over existing new grout inbetween tiles

Hi, My contractor, has applied CeramaSeal tub & tile Caulk over our new existing grout lines inbetween our 4x4 off white ceramic tiles in our shower floor. The reason he did this is because the no sand alabaster grout dried unevenly in color. Dark and light grout lines. He blames this on the grey thinset. The sanded alabaster grout around our 13x13 shower wall tiles dried perfectly. The caulking inbetween 4x4 tiles is even in color and looks great. My concerns are: this is a shower floor - how will it hold up, will it crack, will moisture set over the tiles (there is a nice slope to the tiles and there is a membrane under the mortar)? What about the sand, the grout under the caulk contained no sand and now the caulk contains sand? How will it hold up in cleaning? The lines are less than 1/8 of an inch, about 1/16. He used this caulking around the floor and shower seat and where the walls meet and around the drain. I have not paid him yet, since our glass doors have not been installed yet. I was very pleased with all of the work he has done up until this point. The Grout Getters recommend tub and tile caulk to be used in grout lines where the grout is old or cracking. Please advise us, we are seniors and have very little knowledge of what is correct in this situation. Thank you, victorandjulie

I would appreciate it if you would clarify which Grout Getters company (location) you are referring to.
My company is Grout Getters and we would never put caulking in your grout joints. The grout needs to be taken out and the joints need to be cleaned before re-grouting the area.
Thank you, Debbie
